The beneficial effects of the present invention are:
Characteristic of the electric arc with Automatic-searching anode in welding, therefore existing various welding methods, such as
The super thick stainless-steel sheet (arriving 15mm with a thickness of 6) of high depth weld seam, common argon arc welding machine can not weld, can only be in the table of weld seam
Face forms welding effect, and the middle part of weld seam and bottom welding arc cannot be introduced into, and can only weld 6mm with lower steel plate, therefore can not
Reach good welding effect.Method of the invention increases a becket to alive, in becket near welding gun
The heart can produce superpower longitudinal magnetic field.Electric arc produces violent contractive effect, the electricity of electric arc under the constraint of longitudinal magnetic field
Field intensity significantly increases, to have powerful longitudinal penetration capacity.After electrified metal ring is added, 6 to 15mm can be welded
Therefore longitudinal magnetic field is added in thick stainless-steel sheet between welding gun and welding workpiece, can easily weld high thickness plate material or
Particulate metal material of other welding difficulties.Also, it under the action of hot-wire coil alternating current, is also equipped with to welding workpiece
